Collisions - faculty at Chemeketa
... When two objects collide, they exert forces on one another. If we know the exact forces and time of contact, then we can use Newton’s second law and kinematics equations to predict the subsequent motion of the objects. But the exact forces exerted can be extremely difficult to measure, and they ofte ...

... Begin by choosing the positive direction as down. That seems reasonable since the fire fighter will slide down the pole and not up the pole. The two forces on the fire fighter are his weight, W=mg, which acts downward, the force of sliding friction, f, which acts upward ( ie the friction force oppos ...
